2014-03-14virtio-scsi: actually honor sense_size from configuration spacePaolo Bonzini1-1/+3
We were always truncating the sense size to 96 bytes. Reviewed-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-01-15virtio-scsi: Prevent assertion on missed eventsEric Farman1-1/+1
In some cases, an unplug can cause events to be dropped, which leads to an assertion failure when preparing to notify the guest kernel. Signed-off-by: Eric Farman <farman@linux.vnet.ibm.com> Cc: qemu-stable@nongnu.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-01-15virtio-scsi: Cleanup of I/Os that never startedEric Farman1-0/+4
There is still a small window that occurs when a cancel I/O affects an asynchronous I/O operation that hasn't started. In other words, when the residual data length equals the expected data length. Today, the routine virtio_scsi_command_complete fails because the VirtIOSCSIReq pointer (from the hba_private field in SCSIRequest) was cleared earlier when virtio_scsi_complete_req was called by the virtio_scsi_request_cancelled routine. As a result, the virtio_scsi_command_complete routine needs to simply return when it is processing a SCSIRequest block that was marked canceled.

2013-12-09virtio-scsi: QOM realize preparationsAndreas Färber1-7/+7
Rename qdev -> dev since that's what realize's argument is called by convention. No need to keep more "qdev" around than necessary. Avoid duplicate VIRTIO_DEVICE() cast. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-12-09virtio-scsi: switch exit callback to VirtioDeviceClassPaolo Bonzini1-8/+7
This ensures hot-unplug is handled properly by the proxy, and avoids leaking bus_name which is freed by virtio_device_exit. Cc: qemu-stable@nongnu.org Acked-by: Andreas Faerber <afaerber@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
